In the latest drop, you can specify what the callback function name is.

Is the latest drop the src on page 1 of this posting (the example you have given)?

What happens to the DOM when using scripttagproxy or this version of ext.data.connection in terms of adding scripts dynamically?
I mean, will the script tags add up on each response thus increase memory usage?
If so, can they be removed in a sort of garbage collection, similar to how ext works inernally?

So the new Ext.lib.Ajax.isCrossDomain should make it so that all requests can now be crossdomain? i.e. TreeLoader with a url http://whatever/x.php would automatically generate a GET request to that crossdomain url? Same with store.load?

I am getting ready to find out for myself...will post back unless someone already knows.

I am creating a redundancy server that sits over top of an unlimited number of remote servers. So I have tons of crossdomain.

So when you create grid you specify a url. Can I respecify the url on load with out overriding data.Store.load?
So in otherwords on one refresh the data may be pulled from a remote server. On another refresh, that server may be down and it needs to be pulled from the redundancy server.

I confirmed that uploads work great as you mentioned in the Features Thread. I'll keep my conversation here for now on.

I have an issue where I create a data store and the need to check a status flag to see which url to request data from on each load. So I am using the beforeload event and updating the store.proxy.url. This seems like a good way to achieve this, is there one better?
